HV-Pulse Generators
PG modular series
PG modular system
configurable pulse generator
Modular pulse generator for short pulses designed to cover a wide range of applications.
The generator is a modular daisy chain controlled system consisting of a controlling unit PGctrl and at least one generator module PGmod. The system is expandable to up to ten PGmods, each taking up four power units PPU which provide an output power of up to 1MW per PPU.
To operate the PG modular system, a high voltage power supply (HVPS) is required. Optionally, e.g. for load matching, a pulse transformer unit (PTU) can be connected.
